Eryngium planum ‘Blue Glitter’ is a striking, clump-forming perennial valued for its intense metallic-blue flower heads and architectural presence. Producing a profusion of cone-shaped blooms surrounded by spiky blue bracts, this cultivar offers long-lasting colour and strong structural interest from mid to late summer.
The upright, branching stems rise above neat basal foliage, creating a light yet bold effect in borders and gravel gardens. The flowers are highly attractive to bees and other pollinators and are excellent for cutting and drying, retaining their colour well in arrangements.
Thriving in well-drained soil and full sun, ‘Blue Glitter’ is drought-tolerant once established and well suited to coastal gardens or dry planting schemes. Its vivid colouring pairs particularly well with ornamental grasses and other sun-loving perennials.

Plant images are used for illustrative purposes only, so you know what your plant will look like once fully grown.
You’re purchasing your chosen size of plug plant (by selecting “Plant Size” option above).
Mini Plugs: Each plug is approximately 15mm sq, containing tender young seedlings in need of pricking out and potting on to grow before being planted out.
Midi Plugs: Each plug is approximately 20mm sq, plants are a little more mature than the mini's, can sometimes be planted out if the weather is good and the last frost has passed.
Maxi Plugs: Each plug is approximately 30mm sq, plants are more mature, sometimes over a year old, which can mean well developed root systems and/or fewer leaves due to winter dormancy or cutting back. Generally hardened off and garden ready, though for best results good weather is preferred for planting out.
